Indesign locks up when exporting to pdf

[ruthd13641520]

When I try to export my document to pdf, indesign locks up. It'll jsut stop at a certain percentage and endlessly hang out in the background task manager. I can't get indesign to force quit or restart in this state, the only thing I can do is reboot the whole computer. 

This is happening in indesign 2021 and indesign 2022

You could try 

Exporting the first 50% of the pages if that works try the other 50% of pages - whichever side it fails on is where the issue is. You can keep dividing and conquering the pages to track down the pages with issues.

Other methods to try:

Could you try using File>Export and choose IDML - open that up in InDesign - resave as an indesign document using a new file name.

Does the issue persist?

You could try:

------

Try resetting your preferences:
The easiest way to reset everything is to delete the InDesign preferences: as soon as InDesign starts to boot hold down Shift, Alt, Ctrl (and Apple/Cmd if working on a Macintosh). A dialog will appear asking to delete the InDesign Preferences, select 'Yes' on this dialog.

Rollback to previous version does it work again?

You can export as single pages. The page after the last Page causes the problem.
